I. The State's Submittal

A. What statutes did the state submit for approval?

The Governor's designee, the Nevada Department of Conservation and Natural Resources, Division of Environmental Protection (NDEP), submitted a large revision to the applicable SIP on January 12, 2006. On March 23, 2006, the Nevada SIP submittal dated January 12, 2006 was found to meet the completeness criteria in 40 CFR part 51 Appendix V, which must be met before formal EPA review. On March 24, 2006, the NDEP submitted an additional revision consisting of a definition found in Title 0, Preliminary Chapter of the General Provisions of the NRS. On May 17, 2006, the submittal dated March 24, 2006 was found to meet the completeness criteria in 40 CFR part 51 Appendix V. The primary purpose of these revisions is to clarify and harmonize State and federally enforceable requirements. Because these revisions incorporate so many changes from the 1970s and 1980s vintage SIP regulations, EPA has decided to review and act on the submittal in a series of separate actions. The first such action was finalized in the Federal Register on March 27, 2006, (71 FR 15040). The remaining portions of the submittal will be acted on in future Federal Register actions.

The following table lists the Nevada Revised Statutes (NRS) addressed by this proposal with the dates they were submitted by NDEP.

B. What is the regulatory history of the Nevada SIP?

Pursuant to the Clean Air Amendments of 1970, the Governor of Nevada submitted the original SIP to EPA in January 1972. EPA approved certain portions of the original SIP and disapproved others under CAA section 110(a). See 37 FR 10842 (May 31, 1972). For some of the disapproved portions, EPA promulgated substitute provisions, referred to as Federal implementation plan (FIP) provisions, under CAA section 110(c).

The original SIP included various rules, codified as articles within the Nevada Air Quality Regulations (NAQR), and various statutory provisions codified in title 40, chapter 445 of the Nevada Revised Statutes (NRS). In the early 1980's, Nevada reorganized and re-codified its air quality rules as sections within chapter 445 of the Nevada Administrative Code (NAC). Today, Nevada codifies its air quality regulations in chapter 445B of the NAC and codifies air quality statutes in chapter 445B of title 40 of the NRS.

Nevada adopted and submitted many revisions to the original set of regulations and statutes in the SIP, some of which EPA approved on February 6, 1975 at 40 FR 5511; on March 26, 1975 at 40 FR 13306; on January 9, 1978 at 43 FR 1341; on January 24, 1978 at 43 FR 3278; on August 21, 1978 at 43 FR 36932; on July 10, 1980 at 45 FR 46384; on April 14, 1981 at 46 FR 21758; on August 27, 1981 at 46 FR 43141; on March 3, 1982 at 47 FR 9833; on April 13, 1982 at 47 FR 15790; on June 18, 1982 at 47 FR 26386; on June 23, 1982 at 47 FR 27070; on March 27, 1984 at 49 FR 11626. Since 1984, EPA has approved very few revisions to Nevada's applicable SIP despite numerous changes that have been adopted locally. As a result, the version of the rules enforceable by NDEP is often quite different from the SIP version enforceable by EPA.

C. What is the purpose of this proposed rule?

The purpose of this proposal is to bring the applicable SIP up to date. We are proposing to approve the statutes contained in Nevada's January 12, 2006 and March 24, 2006 submittals.

II. EPA's Evaluation and Action

A. How is EPA evaluating the statutes submitted for approval?

We have reviewed the statutes submitted by NDEP on January 12, 2006 and March 24, 2006 for compliance with the CAA requirements for SIPs in general set forth in CAA section 110(a)(2) and 40 CFR part 51 and also for compliance with CAA requirements for SIP revisions in CAA section 110(l) and 193.

B. Do the statutes meet the evaluation criteria?

We believe the NRS statutes listed in the table are consistent with the relevant policy and guidance regarding enforceability and SIP relaxations. The TSD has more information on our evaluation.

C. Public Comment and Final Action

Because EPA believes the Nevada SIP will continue to fulfill all relevant requirements, we are proposing to fully approve the submitted revisions in accordance with section 110(k)(3) of the Act. We will accept comments from the public on this proposal for the next 30 days. Unless we receive convincing new information during the comment period, we intend to publish a final approval action that will approve these statutes into the federally enforceable SIP.

III. Statutory and Executive Order Reviews

Under Executive Order 12866 (58 FR 51735, October 4, 1993), this proposed action is not a “significant regulatory action” and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use” (66 FR 28355, May 22, 2001). This proposed action merely proposes to approve state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this proposed rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule proposes to approve pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4).

This proposed rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does not have substantial direct effects on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various Start Printed Page 33416levels of government, as specified in Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely proposes to approve a state rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Clean Air Act. This proposed rule also is not subject to Executive Order 13045 “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), because it is not economically significant.

In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the Clean Air Act. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This proposed rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.).
